The digital attenuator can adjust the signal level of the circuit in 0.25dB steps without interrupting the circuit. It can also be used as an in-machine attenuator for instruments and equipment to adjust the power level in the test system. It has a small size. , high precision, stability and reliability. It uses OLED to display the attenuation, and the attenuation can be controlled by the host computer. Technical indicators: 1. Working frequency: LF-6GHz 2. Attenuation adjustment range: 0-31.75dB 3. Attenuation step: 0.25 (dB) 4. Insertion loss: ≤1.5dB (the insertion loss at the high-frequency end will be larger) 5. Standing wave ratio: ≤1.4 6. Attenuation accuracy: ±0.25dB Max 7.
